Abstract: 626,510. Mechanical stokers. THOMPSON (TRIUMPH STOKER), Ltd., J., and PEARSALL, H. E. March 21, 1947, No. 7827. [Class 78 (i)] In a mechanical stoker a number of cams are adjustable by means of rotary screws carried by a carrier member adapted to be rotated about its own axis for the cams to operate the trigger of a spring-loaded shovel, the rotary adjusting screws being adapted to adjust each cam individually on the carrier in relation to the carrier axis to a required setting. As shown, the carrier member comprises a disc 6 secured on a driving shaft 5. The disc has four radial slots 7 each fitted with an adjustable screw 10 on which is mounted a bolt 16 carrying a cam 17.

Title: Improvements in or relating to a method of and apparatus for comparing the peak factors of alternating currents and voltages
IPC: G01R1/30
Filed: 1938-03-14
Abstract: 512,787. Current and voltage measurements. ELLIOTT BROS. (LONDON), Ltd., and SHOTTER, G. F. March 14, 1938, No. 7900. [Class 37] The peak factors of two alternating current and, or, voltage waves are compared by applying the waves, successively, to an ammeter 1 (measuring R.M.S. valves) in series with a resistance 2, and adjusting the ammeter circuit, e.g., by means of a variable resistance 3, so that the current flow is the same for each applied wave, the peak factor in each case being proportional to the amount of the series resistance 2 that must be connected across a device 4 to initiate striking or breakdown thereof. The device 4 may be a neon tube, a grid gas filled relay or other device which strikes or breaks down at a definite peak voltage and indicates that striking or breakdown. The respective waves are connected in circuit by terminals 6-7, 11-12, and a double-pole change over switch 8-8, an auto-transformer 9 and potential divider 10 being provided, if required, for one of the waves for adjustment of the current in the meter 1. A current wave to be compared may, e.g., be connected by a current transformer to the terminals 11, 12. The resistance 2 is calibrated and the wiper contact thereof carries a pointer to read off the resistance connected across the device 4. The apparatus is of particular use for testing and adjusting the peak factors of voltage and current in testing circuits for instruments such as power meters to agree with the corresponding peak factors of the supply circuit on which the meters are to be used. Thus the peak factor of the supply voltage across terminals 13, 14, Fig. 2, could first be compared with that of the test circuit voltage across terminals 16, 17, derived from the supply by a transformer 15. The current coils of a standard wattmeter and of meters under test 19 are connected across the terminals 16, 17 and the peak factor of the current therein could then be compared with that of the supply voltage by means of a current transformer 20, the testing circuit then being adjusted at 18 to equate the respective peak factors. The voltages across terminals 13-14, 16-17, 21-22 could also be compared with a pure sine wave across terminals 24-25 derived in known manner from the supply 13-14.
Patent GB-568292-A (GB)
Title: Treatment of hydrate-forming gases
IPC: C07C7/152
Filed: 1942-06-11
Abstract: Hydrate forming hydrocarbon gases are converted into hydrates by treatment with water and the hydrates are maintained in a stream of a liquid carrier which is pre-cooled considerably below normal atmospheric temperature and then brought into contact with the hydrates.  To form small crystals of hydrates the gas and water are brought into contact in presence of a non-aqueous carrier, preferably by first emulsifying the water with the carrier, and the carrier, which may be a mineral oil fraction such as kerosene, gas oil, or a light lubricating fraction, serves to convey the hydrates from the converter to a storage vessel.  Thus a gas containing methane, ethane, propanes and butanes together with impurities such as hydrogen sulphide, carbon dioxide, helium, oxygen and nitrogen, is introduced along with a mist or emulsion of water at the top of a converter which is kept at 35-40 DEG  F. and 400-650 lb. per sq. in. The specific gravity of the carrier is preferably the same as that of the hydrates, and an emulsifying agent such as a soap or organic salt may be added.  The hydrates may be cooled in the storage zone and kept at about 25 lb. per sq. in. and the hydrocarbons are released by reduction of pressure or by heating.  Specification 568,290 is referred to.
